Background
Because pure copper conductors are expensive and galvanized steel has poor corrosion resistance, copper-clad steel is a novel bimetal composite material, and the copper-clad steel not only has the high strength, excellent elasticity, larger thermal resistance and high magnetic conductivity of steel, but also has better electrical conductivity and excellent corrosion resistance of copper, so that a large amount of copper-clad steel materials are adopted in domestic and foreign grounding materials.
The chinese patent application No. 201710133600.5 discloses a method for preparing a large-diameter tin-copper steel wire by continuous hot-dipping tin, wherein an acid washing and alkali neutralizing process is required in the copper casting process of step (2), and the acid and alkali used in the process not only pollute the environment, but also may exist on the surface of the steel in a small amount, and form bubbles between copper and steel during copper casting, thus affecting the matching reliability of the copper and the steel.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide an acid-free and alkali-free copper-clad steel processing technology which improves the quality of finished products, reduces the environmental pollution and improves the processing efficiency.
In order to achieve the purpose, the invention provides the following technical scheme: the steps are as follows,
(1) the first time of wire drawing, polishing, boronizing, heating and dedusting the steel wire rod in sequence, and then manufacturing a steel disc round wire by using a wire drawing machine;
(2) casting copper, namely straightening, polishing and dedusting the round steel wire of the steel disc, and then feeding the round steel wire into a copper casting furnace to continuously cast the round steel wire into copper-coated steel;
(3) drawing the copper-coated steel into a copper-coated steel wire coil by using a drawing machine for the second time;
(4) and (4) performing heat treatment, namely putting the copper-clad steel wire rod into a vacuum annealing furnace for heating to obtain the copper-clad steel wire rod.
Through adopting above-mentioned technical scheme, in (1), by the polishing, the boride, heating and dust removal are replaced, the boride not only can carry out demagnetization with polishing back steel, can also get rid of most sweeps along with the boride solution, accomplish the work of getting rid of most oxide layers, cooperate subsequent heating and dust removal, make the sweeps can not get into the wire drawing machine along with steel, and, (1) reduce required oxide layer removal volume in (2), so only need polish once more, remove dust and can realize better oxide layer effect, save "pickling, alkali neutralization" step among the traditional step, thereby avoided the pollution that the acid-base caused the environment, also avoided a small amount of acid-base that exists on the steel surface, form the bubble between copper and steel when the cast copper, influence finished product quality.
The invention is further configured to: (5) and (3) forming a film, cleaning the copper-coated steel wire by using ultrasonic equipment, soaking the copper-coated steel wire until a gold oil protective agent is formed, drying, curing and rolling.
By adopting the technical scheme, the film forming process is added, so that the surface of the copper-clad steel wire rod can not be oxidized for a long time after the copper-clad steel wire rod is processed, and the copper-clad steel can be ensured to continuously maintain excellent grounding performance.
The invention is further configured to: in the step (2), the copper casting furnace heats the copper liquid to 1120-1180 ℃.
By adopting the technical scheme, the temperature of 1120-1180 ℃ is preferably selected as the heating temperature of the copper liquid, so that the copper liquid has a better coating effect on steel.
The invention is further configured to: in the step (4), the temperature of the annealing furnace is 650 ℃ to 690 ℃.
By adopting the technical scheme, the temperature of 650-690 ℃ is preferably selected as the heating temperature of the annealing furnace, so that the copper-clad steel has better processing performance.
